Abstract
A positive electrode active material for a secondary battery and a secondary battery including the same are provided. The positive electrode active material for a secondary battery includes on the surface of a core, a surface treatment layer composed of a B and Si-containing amorphous oxide, and thus may exhibit reduced moisture reactivity, improved thermal and chemical stability, and high-voltage stability.
